I've recently noticed the little help icons that have started showing up throughout the AdWords accounts. If you hover your mouse over them, some information is displayed.

Useful?

Most of them are more than a little basic, to put it mildly.

And some of them are less than helpful.

Example: the info displayed next to the inactive keyword notification tells you nothing, but does offer links to more information.

Earth shattering? No. But it appears that Google are polishing and refining their help centre, which is enormously useful.

Anything that gives AdWords account holders more useful information has to be a good thing.
